Summary
Tannins, plant polyphenols, can impact animal digestion and gut health. This review explores their effects and applications in ruminant nutrition, offering insights into their use as an alternative to antibiotics.
Area of Science:
- Agricultural Science
- Animal Nutrition
- Plant Biochemistry
Background:
- Tannins are plant-derived polyphenols with varying molecular weights.
- They can bind macromolecules like proteins and carbohydrates, affecting nutrient digestion.
- Tannins are classified as hydrolysable or condensed tannins.
Purpose of the Study:
- To review the existing literature on tannins.
- To examine the effects of tannins on animal intake and digestion.
- To explore the application and efficacy of tannins in ruminant nutrition.
Main Methods:
- Literature review of scientific studies on tannins.
- Analysis of tannin classification and chemical properties.
- Evaluation of research on tannin effects in monogastric, poultry, and ruminant animals.
Main Results:
- Tannins can act as anti-nutritional factors, particularly in monogastric and poultry.
- Proper application protocols show positive effects on gut health and microbial ecosystems.
- Variability in tannin efficacy is influenced by multiple factors, including structure and application.
Conclusions:
- Tannins have complex effects on animal nutrition, influenced by their chemical structure and interactions.
- When used appropriately, tannins can offer benefits for gut health and production in ruminants.
- Plant tannins represent a potential alternative to in-feed antibiotics in animal agriculture.

The tonicity of a solution determines if a cell gains or loses water in that solution. The tonicity depends on the permeability of the cell membrane for different solutes and the concentration of nonpenetrating solutes in the solution within and outside of the cell. If a semipermeable membrane hinders the passage of some solutes but allows water to follow its concentration gradient, water moves from the side with low osmolarity (i.e., less solute) to the side with higher osmolarity (i.e.,...

Tonicity describes the capacity of a cell to lose or gain water. It depends on the quantity of solute that does not penetrate the membrane. Tonicity delimits the magnitude and direction of osmosis and results in three possible scenarios that alter the volume of a cell: hypertonicity, hypotonicity, and isotonicity. Due to differences in structure and physiology, tonicity of plant cells is different from that of animal cells in some scenarios.
